COAT-LOCK.

SPECIFICATION forming part of Letters :Patent No. 646,066, dated March27, 1900.

Application filed November 20, 1899. Serial No. 737,575. (No model.)

To all whom it may concern.'

Be it known that l, DAVID E. CATHRELL, a citizen of the United States,residing at Boston, in the county of Su'olk and State of Massachusetts,have invented new and useful Improvements in Coat-Locks, of which thefollowing is a specification.

The object of this invention is to provide a coat-hook upon which anovercoat may be hung and to which said overcoat may be locked to preventits being stolen.

The invention consists in means for locking an overcoat to the hook uponwhich it is hung.

The invention further consists in a combination and arrangement of partswhich renders it impossible to withdraw the key from the look until theovercoat-locking mechanism has been actuated.

The invention still further consists in the combination and arrangementof parts set forth in the following specification and particularlypointed out in the claims thereof.

Referring to the drawings,Figure 1 is a front elevation of my improvedcoat-lock with the plate removed from said lock to show the mechanismthereof. Fig. 2 is a longitudinal section taken on line 2 2, Fig. 1,looking toward the left in said ligure. Fig. 3 is a View similar to Fig.1, with the several parts in the positions assumed by them when the coatis hung thereon and the device is locked. Fig. 4 is a section taken online 4 4, Fig. A3, looking toward the right in said figure. Fig. 5 is aperspective View of a portion of the locking mechanism. Fig. v6 is afront elevation of the locking plate and chain. Fig. 7 is a frontelevation of a portion of myimproved coat-lock similar to Fig. l, with aportion of the casing shown in section. Fig. 8 is a detail frontelevation of the key and a portion of the casing which covers thelocking mechanism. Fig. 9 is a detail section taken on line 9 9, Fig.8,- showing the key in elevation and a. portion of the casing insection. Fig. 10 is a crosssection taken on line 10 10, Fig. 9.

Like numerals refer to like parts throughout the several views of thedrawings. Y

In the drawings, 1 is the hook, upon which the coat is hung. Said hookis formed upon a slide 2, which slides in ways 3 upon a fixed casing 4.Said hook has a projection 5 thereon, said projection 5 having anotherprojection 6, which extends vertically, Fig. 1, from the portion 5 andin front of the bolt 7 of an ordinary locking mechanism, (not shown inthe drawings in detai1,) being covered by the plate 8, any ordinarylocking bolt and mechanism being sufficient for the purpose.

As shown in Fig. 1, when the coat is not hung upon the hook 1 the slide2 and projections 5 and 6 are held up against a stop 9 by a spiralspring 10, which bears against the under surface of the projection 5,holding the slide 2 and hook l, also the projections 5 and 6, up againstthe stop 9, the projection 6 being directly in front of the locking-bolt7 and preventing said bolt from being thrown to the left by the key 11.lt is evident, therefore, until the weight of the coat upon the hook 1moves lthe latter downwardly to the position shown in Fig. 3 that thebolt 7 cannot be thrown to the left by the key 11.

A locking-chain lever consisting of a hat piece of metal 12 is pivotedat 13 to the casing 4 and has a locking-chain 14 attached to the lowerend thereof, said chain terminating in a locking-plate 15.

When the coat is hung upon the hook 1 and the slide 2 and theprojections 5 and 6 have been drawn down out of the path of thelocking-bolt 7, the locking-chain 14 andl lockingplate 15 are carriedthrough the coatsleeve from the top to the bottom of said sleeve and thelocking-plate 15 is slid into the slot 16 in the top of the casing 4.The slot 16 is closed by a swing-plate 17, which is kept up in theposition shown in Figs. 1 and 2 by a spiral torsional spring 18. Whenthe locking-plate 15 ispushed through the slot 16 into the casing 4, asshown in Figs. 3 and 4, it will push to one side the flat spring 19,which previous to the introduction of said locking-plate stood Vin theposition shown in Fig. 2 and directly in the path of the looking-bolt 7,so that said locking-bolt could not be thrown to the left by the key 11until the locking-plate 15 had been inserted through the slot 16 and thespring 19 pushed to the right, Fig-2, into the position shown in Fig. 4.It is therefore evident that until the locking-plate l5 is insorted inthe casing, as described, the locking-bolt 7 cannot be thrown to theleft, Fig. 1, by the key 11.

Thelocking-chain 14 is made of such length IOO that it cannot be passedthrough the coatsleeve and the locking-plate 15 inserted in the casing,as described, without tipping the locking-chain lever 12 from thevertical position (shown in Fig. 2) to the canted position. (Shown inFig. 4.)

The locking-chain lever 12 is pivotally connected at 2O to alocking-lever 21, pivoted at 22 to a lug 23, fast to the casing 4.

rlhe upper end of the locking-lever 21 has a projection 24, which standsin front of the locking-bolt 7 when the parts are in the p0- sitionshown in Fig. 1 and is thrown out of the path of said bolt, as shown inFigs. 3 and 4, when the locking-lever 2l is tipped by the locking-chainlever 12, as shown in Figs. 3 and 4. It will thus he seen that when thecoat is hung upon the hook 1, the lockingplate 15 introduced into thecasing 4, and the locking-chain lever 12 tipped at an angle, asdescribed, the lock-bolt 7 can be thrown by the key 1l to the left, Fig.1, into the position shown in Fig. 3, and the end of said lock-bolt 7will enter the recess 25 in said locking-plate 15 and the key can bewithdrawn from the lock, leaving the lockingplate 15 locked to thecasing 4 by the lockbolt 7, and it will thus be seen that the coatcannot be removed from the hook without the aid of the key 1l to throwback the lockbolt 7, so that the locking-plate 15 can be withdrawn fromthe casing 4 and slipped through the sleeve of the coat to disen gage itfrom the hook 1.

The key 11 is inserted in a slot 35 in the plug 30, said plug beingconnected to the locking mechanism. (Not shown.) Said plug 30 turns in acylindrical projection 3l upon the portion of the casing 8 covering thelocking mechanism. Upon the front of the projection 31 is a flange 32,which enters a notch 33 in the key 11. Said flange has a notch 34therein, which allows the key l1 to be introduced into the slot 35 inthe plug 30 when said slot is inline with said notch, this alinementoccurring when the lock-bolt 7 is thrown to the left and when the partsare in the relative position shown in Fig. 3. The key can then beremoved from the lock or inserted therein, and in no other position. Thepin 36, fast to the projection 31, enters a groove 37 in the plug 30 andforms a stop for said plug, so that when the key is turned to theposition shown in Fig. 1 it can be turned no farther toward the right onaccount of one end of the groove in the plug 30 coming against the pin36, and in turning the key to the left from the position shown in Fig. 3the other end of the groove comes against the pin 36 and prevents thekey from being turned any farther to the left than shown in said Fi". 3.It will therefore be noted that the key cannot be removed from the lockwithout pulling down the hook 1, inserting the locking-plate 15, tippingthe locking-chain lever 12 to the position shown in Fig. 4, and turningsaid key to the position shown in Fig. 3, when it will be in line withthe notch 34 and it can be Withdrawn from the lock. Any one of thesethree movements would be inoperative by itself as far as removing thekey from the lock is concerned, as all three of the movements have to bemade in order to make it possible to turn the key 11 to the positionshown in Fig. 3, whence it can be disengaged from the lock.

It is evident that the locking-chain 14 might be attached directly tothe locking-lever 2l without departing from the spirit of my in vention.

Upon the casing 4 I have provided a hook 27, having a verticalprojection 2S thereon, the object of the hook being to hold a hat and ofthe projection to prevent said hat from swinging around in front of theface of the lock.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a coat-lock, a casing, a coat-hook slide movable therein, a hookfast to said coat-hook slide, and means for keeping said coat-hook slidenormally raised, a reciprocatory lockbolt, means for moving saidlock-bolt across the path of movement of said coat hook slide, and aprojection upon said coat-hook slide which stands in the path ofmovement of said lock-bolt when said coat-hook slide is raised.
